• If you are trying to use Boolean operators, they must be ALL CAPS: ((doi chieu) OR (ho chieu)) xanh - hanh ((trang va) OR (luan van)) nhung huong ban chat co~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) xanh - hanh ((trang va) or (luan van)) nhung huong ban chat co~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) xanh - hanh ((trang va) or (luan van)) nhung huong ban chat co*.
